About this deal

D Klahr, 2000, Exploring Science: The Cognition and Development of Discovery Processes, Cambridge , MA:MIT Press

In the early 1980s, the psychology of science community led by the laboratory of David Klahr at Carnegie Mellon University adopted the Big Trak as a research vehicle for the study of Instructionless learning, Scientific discovery, View application, Cognitive development, and Dual Space Search.

There were no LED displays or ways to display program instructions, beyond actually running the program, which was done by pressing "GO". Each command inputted will be added next to the previous command inputted, allowing the operator to build a list of commands up to 16 commands.

The original Big Trak uses a 9 volt battery to power its microcontroller, while the 4 D cell batteries are used to power its electric motors. This electrical isolation helps prevent any electrical noise from the motor, speaker, and lamp from resetting or interfering with the microcontroller. [11] The re-release Zeon version uses only 3 D cell batteries to power both its microcontroller and electric motors, while the Bigtrak Jr version only needs 3 AA batteries to power both its microcontroller and electric motors. BIG TRAK / bigtrak is a programmable toy electric vehicle created by Milton Bradley in 1979, resembling a futuristic Sci-Fi tank / utility vehicle, possibly for use on the Moon or a Planetoid style environment. [1] The original Big Trak was a six-wheeled ( two-wheel drive) tank with a front-mounted blue "photon beam" headlamp, and a keypad on top. The toy could remember up to 16 commands, which it then executed in sequence. There also was an optional cargo trailer accessory, with the UK version being white to match its colour scheme; once hooked to the Bigtrak, this trailer could be programmed to dump its payload. However, the hardware on the late 1970s and early 1980s Bigtraks does not seem to be capable of processing any In command. [12] Computer control
